OHAPLET-ANCHORING DEVICE FOR FOUNDRY-FLASKS.

Specification of Letters Patent.

Patented June 30, 1908.

Application filed July 26, 1907. Serial No. 385,717.

To all whom it may concern:

Be it known that I, TnoMAs B. HARKINS, citizen of the United States, andresident of Bristol, Bucks county, State of Pennsylvania, have inventedcertain new and useful Improvements in Chaplet-Anchoring Devices forFoundry-Flasks, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, of whichFigure 1 is a plan view showing a preferred form of my chaplet anchoringdevice. Fig. 2 is a section through the upper portion I or cope of aflask or mold, with a core, the

chaplets extending upwardly from the same, together with my chapletanchoring device in elevation. Fig. 3 is a section on the line ac:c,Figs. 1 and 2.

The object of this invention is to provide a novel and efficient meansfor anchoring or retaining the chaplets of a mold flask in place, so asto revent the core from being shifted within tie flask, in the moldingoperation.

1 is a portion of the cope of a flask having a core 2, a space, 3, inwhich the molten metal is to be flowed, surrounded by the sand, 1, whichis penetrated by one or more (in this instance, two) verticallyextending chaplets, 5, of well known construction. Clamped upon the topof the opposite sides of the flask, 1, by the L-shaped bars, 6, are bars7, having, extending therefrom respectively, across and above the top ofthe flask, bars, 8. These bars, 8, have, slidably mounted thereon, a boxor boxes, 9, adapted to be clamped to said bars at any position ofadjustment desired, by suitable clamping screws, 10. Screwed throughthese boxes are screws, 11, having, at their lower ends, buttons orheads, 12, swiveled thereon, as seen in Fig. 3.

The boxes, 9 are adjusted to such position along the bars, 8, that thebuttons or heads, 12 will come over the chaplet rods, 5; whereupon thescrews, 11, are screwed downwardly, so that said buttons come againstthe upper ends of the said chaplet rods. As the said buttons, 12, areswiveled to said screws, 11, they may be clamped ti htly down againstthe chaplet rods, 5, without disturbing the position of the latter, byreason of the rotation of said screws.

In the drawings, I have shown the bars, 8, pivotally secured to thebars, 7, by bolts, 13. Although this is preferable, so that the angle ofthe said bars, 8, with relation to the sides of the flask may beadjusted where the chaplets are out of line, said bars, 8, might berigidly secured to or integral with the bars, 7. I also remark that thenumber of the boxes, 9, used upon the bars, 8, may be varied, accordingto the number of chaplets, 5, employed in the mold. Of course, where butone chaplet is employed, the rigid construction of the bars, 8, would bepreferable. Other means than that shown may, of course, be employed tosecure the bars, 7, to the sides of the flask, the construction shown inFig. 2 being simply one well known arrangement.

A manifest advantage of my construction is that the anchoring device isadjustable to fit flasks of various widths; that is, when the boxes, 9,are loosened u on the bars, 8, the bar portions, 7, may e drawn apart orbrought closer together, in accordance with the width of the flask.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. A chaplet anchoring device comprising the parallelbars, means for securing the oposite ends of each of them to the sidesof a ash, together with the box mounted and adapted to slidelongitudinally upon said bars, means for securing said box in anyposition of adjustment, and the screw passing through said box, andwhose lower end is ada ted to bear u on a chaplet bar, substantial y asand for t 1e purpose set forth.
